Abstract
Multi-channel reproduction of spatial audio can be approached in
several ways. Typically, several loudspeakers are placed in a listening
space and a discrete signal is sent to each. Many loudspeaker
configurations and signal capturing/generation techniques exist.
Systems vary from the omni-prevalent two channel stereo to large Wave
Field Synthesis loudspeaker arrays. Stereo and quadraphonic
spatialization algorithms are typically based on amplitude panning,
which has recently been extended using vector based techniques. Other
approaches include Ambisonics, which employs spherical harmonics to
decompose the sound field, and Wave Field Synthesis, which is based
on the Huygens Principle of Wave Propagation. Respective systems can
be critically assessed based on attributes such as spatial accuracy,
complexity and practicality.
